BALL CAGE FOR RADIAL BALL BEARINGS.

Application filed September 10, 1921. Serial No. 499,781.

To all whom it may concern:

Be it-known that I, EMIL STAAKE, a subject of the King of Sweden, residing at Gottenborg, in the Kingdom of Sweden, have invented new and useful Improvements in Ball Cages for Radial Ball Bearings, of which the following is a specification, reference being had to the drawing accompanying and forming a part thereof. This invention relates to such ball cages for radial ball bearings which consist of rings placed at either side of the row or rows of balls, respectively, and provided, preferably, with seats for the balls. In ball cages of that kind, as hitherto known, the said rings have been secured to one another by means of screws or loose rivets. The screw connection, however, is insufficient, and the loose rivets are inconvenient to place in the holes to that end provided in the rings, because this must generally take place, after the balls and the cage rings have been placed in the bearing. It has also been proposed to provide the. rings i ball cage which, at the same time as it is simple and cheap in manufacturing, facilitates a reliable connection of the cage rings. The invention consists, chiefly, in this, that lugs or the like are stamped out of the ring material proper, which lugs are bent over and introduced with the free end through holes in the opposite cage ring and riveted. .1 By this a reliable securing of the rings of the ball cage is erformed and no additional materlal, more t an the ring material proper, to is required for forming the rivets.

In the annexed drawing two forms ofembodiment of a ball cage according to this invention are shown. Fig. 1 is an end view of a ball cage according to the one'form of embodiment. Fig. 2 is a longitudinal section thereof, developed in a plan. Fig. 3 is a longitudinal section of a somewhat modified ball cage, developed in a plan.

Fig. 4: is a cross-section thereof. Fig. 5 is a longitudinal section of a further modification developed in plan.

The ball cage -shown in Figs. 1 and 2, consists, in known manner, of two rings 1 and 2 having semispherical seats for the balls. In the form ofembodiment shown, lugs 3 are stamped out of the ring 1, said lugs being bent over and introduced through holes in the opposite ring 2 and riveted. The parts of the rings 1 and 2 located between the ball sockets lie in this form of embodiment close to one another.

The form of embodiment of the ball cage shown in Figs. 3 and 4, by which the parts of the rings 1 and 2 located between the ball sockets lie at a certain distance from one another, difi'ers in other respects from the form of embodiment according to Figs. 1- and 2 by this onlyethat the lugs 3 stamped out of the ring material form also partition walls between the adjacent ball sockets. The lugs 3 forming said partition walls may in this case, preferably, be made wider than in the form of embodiment according to Fig. 1 and provided at the free end with a narrower tongue 4, which is introduced through the hole in the oppositering 2 and riveted.

Obviously, the ball cage may also be made for multiple row radial ball bearings and, furthermore, the lugs forming the rivets may, if desired, be stamped alternately out of both rings. Besides, the lugs may be stamped out at corresponding places in both rings so as to form at each joint a double rivet, whereby the parts of the lugs projecting at the one side of each ring may be bent in opposite directions. The lugs may also, if desired, be'secured to the opposite ring by welding.

I claim: A 1. A ball cage for single or multiple row radial ball bearings, consisting of rings placed at either side of the row or rows of balls, respectively, and provided, preferably, with seats for the balls, characterized by 109 this that lugs or the like are stamped-out of the ring material proper between the edges of the same, said lugs being bent over and introduced with the free end through holes in the opposite cage ring and riveted 105 or welded.

Q eaaee 2. A ball cage according to claim 1 char-' rings extending through holes in the other H5 acterized by the fact that the lugs form parring and engaged fixedly therewith to hold tition walls between adjacent ball sockets. the rings together, said lugs consisting of 3. A ball cage according to claim 1 charportions of the ring separated from the e acterized by the fact that the lugs are metal thereof wholly between the edges of stamped out alternately from both of the the ring and extending laterally to engage ee cage rings. the other ring.

4:- A hall cage for ball bearings eompris-t In testimony whereof I have signed my ing opposing rings adapted to receive the name. 7 7 1o balls between them,'and lugs on one of the EMJIL STAAKE.
